On the way to Multiband Solar Cells
Wladek Walukiewicz of the Materials Sciences Division led the development of the first intermediate band solar cell to demonstrate charge transfer across all three band transitions – valence/intermediate, intermediate/conducting, and conducting/valence. These results open the door to high-efficiency solar cells and multicolor light emitters. Continue reading
